Mum is so determined to keep up appearances that when Dad leaves her ‘to find himself’, she hires an actor to replace him. It's a perfect solution to an embarrassing situation, as long as she uses her imagination to find the extra cash. Mum’s the word. Luckily, the daughter’s far too busy planning the happiest day of her life to notice, but the son smells so many rats he's a loose cannon who must be kept behind closed doors. Keeping the cat in the bag and the skeletons in the cupboard whilst avoiding the elephant in the room tips them over the edge and all of a sudden they are all at sea. And that's when they collide with a Spanish conquistador from the 16th century. How embarrassing is that?
